A dynamic momentum compaction factor lattice in the Fermilab Debuncher ring

In the initial and present design of the Debuncher ring, the momentum compaction factor (α), or equivalently the slip factor η=α-1/γ², was chosen to have a value which is a compromise between the two competing functions of the ring - that of accepting and debunching a large number of p¯s/pulse and subsequently employing stochastic cooling feedback systems to precool before injection into the Accumulator. The goal of this experiment is to reconcile this compromise by changing η between two desired values during each p¯ production cycle
